  • How did I miss that?!

    My timeline is incorrect then. Since the post from sassymetischick.bsky predates the wiki edit, it is more likely that the wiki edit was made in response to this meme, and not the other way around. This pretty invalidates what I said above…

    I still can’t find any evidence of this being an actual trend, but I no longer have a good guess about the origin.




  • Salamander@mander.xyzMtoScience Memes@mander.xyzChat, is this true?

    EDIT: As indepndnt mentioned in a comment below, the OP was posted on February 14, which pre-dates the wikipedia edits. So, my conclusions below about the timeline are not valid.

    Hah, sure, let’s investigate 🕵️‍♂️

    The term ‘Chalchiuhtlicueyecatl’ was added as a potential Aztec name to the English wikipedia page on February 15, 2025, by user ‘Mxn’.

    The description of the edit is the following:

    Frum says the Aztecs had no specific name for the gulf, which is plausible in a practical sense, but Fernández gives a specific religious name and is more of a reliable source on this topic

    If we investigate a bit further, we can see that the term Chalchiuhtlicueyecatl is described to be a name for the ‘Gulf of Mexico’ in the spanish Wikipedia: https://es.wikipedia.org/wiki/Chalchiuhtlicueyecatl

    This page was updated to include the description of Chalchiuhtlicueyecatl as the ‘Gulf of Mexico’ in September 16, 2018. I don’t have access to the citation so I don’t know if the citation specifies if this term is still known/used.

    If you check the history you will find that the same ‘Mxn’ fixed a typo in this page on February 15, 2025.

    So, from this sequence of events it is highly likely that the term ‘Chalchiuhtlicueyecatl’ was included into the Gulf of Mexico wiki page as a result of the user Mxn performing an active search for Aztec names for the Gulf of Mexico, and finding this connection between the term an the gulf by searching on Wikipedia. This information did not come from recent news about the term being used by natives.

    I can find no evidence of native people referring to the gulf of Mexico as ‘Chalchiuhtlicueyecatl’ more frequently or at all. I can find no mention of this becoming viral in Mexico.

    I find it highly unlikely that:

    • User Mxn added an obscure Aztec term to the Wiki page two weeks ago

    AND

    • This same obscure Aztec term coincidentally began being used by Mexican natives, and this trend became popular enough to be noticed by foreign media but not by Mexican media

    More likely…

    • Mxn actively looked for a term and updated the English wiki
    • Someone read the English wiki, thought this would be a nice story, made the meme

    And this concludes my little investigation 🧐


  • Ooh, cool! 😁 That detector seems to be working only in “Geiger mode”, which means that it can count the number of X-rays/Gamma particles but it does not estimate their energy. So, the dedicated devices are still better in that they allow you to identify the source of the radiation by measuring the counts and the energy distribution simultaneously.

    It probably would not be too difficult to build the open gamma detector into something like a pinephone. I don’t think that has been done yet.



  • Yes. The camera pixels generate a current in response to light. You can add some filters to block certain wavelengths of light (like UV) from getting to the camera sensor, and tune the pixels so that they respond more to to specific colors. But X-rays and gamma rays can just pass through the filter. Often they will pass through sensor as well, but, in the cases that they do get absorbed by the sensor, they can also produce a current that to the camera’s readout electronics looks like other light would.

    The gamma detectors I mentioned are very very sensitive. They respond to single X-ray/Gamma ray particles. These detectors can count how many individual particles collide with a small crystal cube every second. These crystals are special in that they produce a very tiny flash of light when an X-ray or gamma particle collides with them. As an added bonus, these sensors can directly measure the energy of the particles by measuring the strength of the flash, and from this information they can construct not only the total counts but also a spectrum. With this extreme sensitivity these detectors can measure small quantities of radiation that come from space, from rocks, and from other materials.

    I looked for a video of a phone going through an X-ray machine, and found these:

    https://www.youtube.com/watch?v=V1YaroH6lHA

    The white specks that you can see near second 25 (first video) and second 34 (second video) could be a result of the X-rays. I am not sure, but it seems reasonable to me. On contrast, when I put my radiacode through the X-ray machine in the airport the radiacode reacts very strongly and becomes saturated.

    Good news! Just got a reply from them and they have increased the connection limit. They did not specify what the new number is, but hopefully it is high enough to not be an issue for the foreseeable future.

    So, if you do run into other similar reports after this comment I would appreciate it if you tag me again.

    Thanks!

    Cost is not the bottleneck in this case… The problem is that I am rather ignorant about the options and their benefits/limitations. Moving the images the first time was painfully slow because of those same rate limits, and I expect the next migration to be the same, so I want to make a better choice next time and would rather find a solution with the current provider 😅
